TO ALL WHOM IT MAY GONCERN:

Be it known that I, WILLAM EMMONS, of Sandwich, in the county of De Kalb, in the State of Illinois, have invented anew and useful Improvement in Concrete-Brick Machines; and I do hereby declare that the following is Ya full and exact description thereof, referencebeing had to the accompanying drawinrvs and to the letters of reference marked thereon, making a part of this specification, in which-A o Figure 1 is an isometrical representation of my invention. v

Figure 2, an isometrical representation of the die and stein, removed from the other parts of the press to to give al clear idea of their construction.

Figure 3, a sectional elevation of the press, taken parallel with the sides A A.

The nature of' my invention consists in a novel arrangement of the li-.l ol' press, together with fnstenings, whereby the surplus concrete, projecting over the mould, muy be cut off by the simple act of closing the lid.

In order that others skilled in the art may rhake and use myinvention, Ihave marked corresponding parts with similar letters, and will now give a detailed description.

A A represent the sides of the machine, which should be malle of iron, and to form the ends of thel mould I I, fig. 3, in the usual manner, and should have the lugs D'D D S cast solid to them, or otherwise rigidly attached in the most substantialmanner for the purpose of sustaining such f 'orce as is necessaryto press a brick. A lid, E, is made to swing ona bolt, C, g.1', and with a, lug, P, for catching over the lug S,vand thus hold the corner of the lid down ou the mould I. The other corners of the lid, being fitted to pass under the lugs D, are firmly held in place during the time a brick is being pressed. That par-trof the stem shown at M should be cast solid to the die E', and with one or more notches, N, for the end of the lever G to lit in, vand Araise the mould- 'or throwing a brick out after it has .been pressed. The lower part, L,'oi` the two-part shank, is made to rest on a commencant-roller, K, figs. 1 and 3, and' to strike against'the part M when said roller and a lever, G, are used to press a brick, there being two guides, J J, projecting outward from the inner sides of the frame A A for the purpose of 'keeping the stem in position. v s l I Operation.

The lid E should be swung around, as seen by the dotted lines X, after which the'mould I I can be filled with concrete, and the surplus cut olf by shutting the lid. Thebrick'is pressed by operating the lever II in the usual manner. When the brick is to be removed from the mould, the lid can be swung open, and thebrick thrown out by tbe lever G.

It will be seen from this latter description that the lower part,`L, of the shank, is not raisedvwhen thc brick is removed, but remains stationary on the cam K, whereby less power is required to raise the pressed brick.

What I claim, and desire to secure by Letters Patent, is-

'Ihe lid E, arranged with a lug, P, and to swing on a bolt, C, in combination with lugs DD D S, and mould I Las and for the purpose set forth.
